How to prevent piglet edema

New sub-organisms can be injected, and they can also be treated with drugs**, and magnesium sulfate can also be taken orally, which can help **, and attention should be paid to disinfection, and vaccines should also be injected, and the spread of the virus should also be noted.

You can give the piglets some rich protein and calcium things, you can supplement some trace elements, improve the immunity of piglets, it is best to choose breastfeeding, you can give the piglets to eat something good to digest and absorb, and you can also give the piglets some vaccines can play a preventive role.

When encountering such piglets, you can only give up, because such a disease is very serious, it is difficult to **, first of all, don't feed too much water to the pig at ordinary times, and don't let the weather be too hot.

Give the pig some medicine or ask the veterinarian to take a look. You can clean the pigsty, then ventilate it frequently, and feed the pigs some clean food.

First of all, we should provide a clean and comfortable environment to recuperate, and give the pig some relevant drugs, and the usual diet should be supplemented with more protein and water, usually the environment and temperature regulation of the pig house, and to ensure that it is clean, can be effectively prevented.

It must be dealt with in a timely manner, disinfected regularly, and a reasonable feed should be used, and sufficient nutrition should be added to the piglets, especially in the early stage.

First, the piglets are supplemented with selenium 1-3 days after birth. After weaning, piglets switch from liquid feed to solid concentrated feed, and the amount of food is too large, resulting in an imbalance in the piglet's intestinal microflora. The same frequency is higher, and the frequency is lower when the temperature is stable; Vitamin B and sodium selenite are added to the feed less frequently.

Edema disease is the main disease affecting the efficiency of pig farming and the main cause of piglet death. It is important to understand the pathogenesis of edema disease in piglets. These undigested feeds are also a source of nutrients for harmful bacteria to multiply.

After sodium acetate, we should try to extend the feed conversion time as long as possible to reduce the pressure of feed conversion. During this period, pathogenic E. coli will take the opportunity to invade the piglets, and the head of the diseased piglets will become obese and edematous, and the mortality rate can reach up to 50%, or even 80%. Asthma can be said to be a big killer of piglet health!

Its effect is to inhibit the proliferation of harmful bacteria. For example, swelling sickness is mainly caused by food problems. The onset of oncological diseases is divided into four stages:

1.Edema of gastric curvature.

You can anatomically see the occurrence of fundus edema. The first symptom of the pig is vomiting, which is temporary. Intestinal edema.

Currently, the toxins in the feed are absorbed by the intestines, causing transient diarrhea. Some people recover faster through life**. With the usual intramuscular injection of milk powder for storage vaccines.

2ml head for 7-11 days at a time, 2ml head at a time for 25 days, to prevent a failure of immunization, the lowest cost, pig edema is a regional fatal disease of pigs, and has a lot to do with the feeding of pigs. The main reason is that the piglets have a better quality diet and <>

Without a certain amount of nutrition, the quality of feed protein deteriorates, and the number of diseases is caused by E. coli. Coke. However, this e.

E. coli does not damage the gastrointestinal tract of pigs, but it can damage the brains of pigs. Pigs have neurological symptoms of encephalitis, which are easy to appear when they are relatively large, and you can find that the most important point is that the pigs with the best growth are the pigs with encephalitis, so they are also the most sad; Enterobacteriaceae iron preparations can also be injected into intramuscular pigs with the addition of 1 ml of 1 1000 sodium selenite. In 15-day-old piglets, selenium was supplemented twice, 2 ml head.

First of all, we must ensure the cleanliness of the environment, but also ensure good ventilation, and secondly, we must add some drugs to increase immunity in the feed, and also provide clean water, and also disinfect in the cage every day.

To keep the pig house clean, ventilate frequently, spray the pig house with disinfectant, give the pigs some medicine, and give the piglets nutritious food.

To ensure the cleanliness of the pigsty, to clean the pigsty in time, to strengthen ventilation, you can feed some antibiotics to the piglets, to feed the piglets some nutritious food.

It can be prevented with medication, or by observing the basic manifestations of the disease, but also by finding the source of infection, cleaning the pig house regularly, and paying attention to the spread of bacteria.

Porcine edema disease is an acute fatal disease of pigs caused by toxins produced by hemolytic Escherichia coli. When the feed is deficient in vitamins, minerals and trace elements, it leads to the disease of newly weaned piglets, and the fast-growing, fat and fat piglets are the first to develop the disease. Although the incidence rate is not high, often only 1 2 piglets in a litter, and more than 3 piglets get sick, but the mortality rate is extremely high, up to 90% 100%, causing great economic losses to the pig industry.

Symptoms] suddenly onset and a "squeak" scream, fell to the ground and died. In the early stage of the disease, some people are excited to turn in circles, edema of the eyelids, head and neck, muscle spasms of the whole body, angular arch reflexion, movement disorders, unable to stand, fall to the ground, limbs stroke, foaming at the mouth, paralysis and death.

Prevention] 1) Strengthen the feeding management of weaned piglets, and have enough minerals, vitamins and trace elements in the feed, especially selenium and vitamin E. Prevents constipation in piglets. The feed cannot be changed suddenly, etc.

2) Add 500 grams of oxytetracycline hydrochloride to each ton of weaned piglet feed, mix thoroughly, and feed for 7 days.

3) Add 20 grams of florfenicol per 100 kg of feed, mix well and use for 7 days.

4) The pig farm can take the lymph nodes of the sick and dead pigs to the laboratory for bacterial culture, and then do antimicrobial susceptibility tests, select sensitive drugs, and apply them to the whole litter of piglets.

**]1) Take it with 50 grams of magnesium sulfate + 50 ml of water (one time), and then immediately inject streptomycin 10 mg per kilogram of body weight + 2 ml of complex vitamin B injection head, 2 times a day for 3 days.

2) Sodium selenite 1 2 ml per kilogram of body weight + vitamin E 200 mg per kilogram of body weight, intramuscular injection, 1 time every 2 days, 2 times in a row.

3) Neomycin sulfate 250,000 IU head, intramuscular injection, 2 times a day, for 3 days.

Porcine edema disease is an acute "toxic" disease of weaned piglets. The main manifestations are movement disorders, local or generalized paralysis, and edema of the subcutaneous, gastric and mesenteric walls of the head.

Porcine edema disease is caused by toxins produced by a certain serotype of hemolytic E. coli. Generally, it occurs more in summer and autumn, mainly after weaning piglets. The occurrence of swine edema disease is often irregular.

In a piglet herd, some piglets suddenly become ill and die quickly, and may suddenly stop happening. Most of the cases are healthy and well-nourished piglets. It is generally believed that excessive feeding of thick feed after weaning, or sudden change of feed, causes gastrointestinal disorders, disrupts the biological balance between normal intestinal microorganisms, and promotes the reproduction of hemolytic Escherichia coli and the production of toxins, thus inducing the disease.

In the early stage of the outbreak, it is common for swine edema to die suddenly without obvious symptoms. If the onset is slightly slow, the early manifestations are slightly poor spirit, loss of appetite, unsteady walking, sometimes walking aimlessly or in circles, some of the two forelimbs kneel on the ground, the hind limbs are upright, and suddenly jump forward; It often develops into convulsions, falling to the ground suddenly, and moving around on all fours. The body temperature of most sick pigs is not high, and some can rise to.

Eyelids, face, neck edema, ** hyperesthesia, screaming at the touch, slow reaction in the later stage, difficulty breathing, hoarseness, sometimes vomiting, generally more than 2 days of death, slightly older pigs, the disease period can be as long as 5 7 days.

Pathological autopsy changes subcutaneous edema of the eyelids, face, and top of the head, and the incision is grayish-white powder-like, with a thickness of up to centimeters. The gastric wall is markedly edematous, especially in the greater curvature of the stomach and the cardia section, which is jelly-like, and discharges a grayish-white clear fluid, and the thickness of the edema can reach 1 3 cm. The colonic mesenteric edema is obvious, the entire intestinal wall is cool and powdery, and the intestinal mucosa is red and swollen.

Lymph nodes are almost universally edematous.

Among the control measures, the fundamental approach is to strengthen the feeding management of piglets before and after weaning. Piglets should be fed early and trained to eat, so that they can adapt to independent life quickly after weaning. At the same time, after weaning, nutritious and easy-to-digest green feed should be given to avoid sudden changes in feed.

The enclosure should be dry and clean, and special attention should be paid to the hygiene of the feeding trough.

There are many methods of swine edema, but the effect is not obvious. When sick pigs are found, they immediately stop feeding concentrate and take salt laxatives, such as magnesium sulfate, sodium sulfate, etc. When some pig farms are sick, they have received certain effects with streptomycin**.

Cortisone acetate 50 to 100 mg may also be given intramuscularly or subcutaneously in combination with antibiotics and sulfonamides**. Calcium preparations and vitamins are also available. For pigs that have not yet become ill, a certain amount of antibacterial drugs can be added to the feed to prevent the disease.

The best principles of edema disease are desensitization, cardiotonics, bacteriostatic, diuretic, and swelling.

Desensitization can be done with hydrocortisone or dexamethasone, diuretic furosemide (nitrofuranine) or dihydrogram urinary plug, antibacterial sulfonamides are preferred; Secondly, enrofloxacin, lincomycin, etc., and glucose, sodium coffee, selenium and other auxiliaries can be selected

Immediately after the onset of the disease, the feed with high digestibility was fed, and drugs were added to the feed.

Individual**: 10 20 ml of 10% sulfadiazine sodium injection, 50 ml of 50% hypertonic glucose injection, intravenous injection, once a day for 2 3 days, long-acting oxytetracycline, enrofloxacin and other intramuscular injections, 2 times a day for 2 3 days; Or 50% glucose solution 20 40 ml, full edema reduction according to the instructions for use, vitamin B 12 ml, inosine 2 ml, 20% sodium coffee 2 ml, mixed once intravenously. When the neurological symptoms are severe, sedatives such as chlorpromazine hydrochloride and analgin can be injected.

Porcine edema is an acute, fatal disease of weaned piglets, mainly in newly weaned piglets, especially fast-growing and robust piglets. The onset is sporadic, only 1-2 hair diseases in a litter or a group of pigs, the onset is sudden, the initial body temperature rises, and then quickly drops to room temperature or low, often constipation. The characteristic symptom of this disease is edema, which is more common in the eyelids, head, neck, and even the whole body; Visceral edema is common in the stomach wall, especially the greater curvature, cardia and floor of the stomach, and the edema is incised, and there is a layer of transparent or brown-colored and reddish peptone between the mucosa and the muscular layer.

Edema is also seen in the mesocolon, mesenteric lymph nodes, and superficial lymph nodes. Sick pigs mostly show neurological symptoms such as blind walking or turning in circles, ataxia, spasms or convulsions, and then gradually develop into hindquarters paralysis and die in a coma within 1-2 days.

The pathogen of this disease, which is currently believed to be caused by pathogenic Escherichia coli, often lacks enteral adsorption factor, is hemolytic, and contains endotoxins and neurotoxins. In addition, feed sheets.

1. Too much concentrate, vitamin B or E, selenium and other minerals are deficient in this disease. Due to the sudden onset of the disease, the course of the disease is short, the pathogenic mechanism is not very clear, and the general effect is not obvious. At present, no effective preventive vaccine has been developed, and only the cause of the disease can be prevented.

1.Infected sows and infected piglets are the main sources of infection, and the bacteria are excreted in the feces, contaminating feed, drinking water and the environment, and passing through the digestive tract. Therefore, regular feeding of pigs with oxytetracycline, norfloxacin, ciprofloxacin and other drugs or microecological preparations can reduce the pathogenic bacteria in the pig intestine and reduce the pollution of the environment by the bacteria.

2.Piglets 3-5 days before and after weaning or transfer were fed drugs or microecological preparations to control the number of E. coli in the intestine of piglets.

3.Strengthen the feeding management of piglets before and after weaning, and do not suddenly change the feeding conditions when weaning. It is best to use compound feed, and add trace elements and vitamins in moderation, especially pay attention to adding selenium and vitamin E to the feed.

4.Weaned piglets should not use high-protein, high-energy feed, and properly control the amount of feed for piglets with large weight, so as not to cause indigestion, because excess nutrients to the hindgut, will cause E. coli to multiply in large quantities and promote the occurrence of diseases.

5.It is necessary to prevent indigestion caused by cold in weaning and turning piglets, causing intestinal microbial flora disorders and inducing E. coliosis.

It can supplement nutrition to pigs, improve the body immunity of pigs, and use drugs to carry out **, the best effect.

I think we must ask a more professional veterinarian to come to **, and we should also find out ** in time, and then prescribe the right medicine, so that the effect is better.

Be sure to pay attention to the choice of medicine, and at the same time you should go to the veterinarian for **, and to understand the symptoms of this disease, you must prescribe the right medicine.

The following prevention and control methods can be used for reference:

1) For pigs of the same group of similar ages, as long as one of them is diagnosed with edema, the whole herd will be injected with long-acting oxytetracycline (delisian), or sulfadiazine (general therapy), or doxycycline, or neomycin sulfate, or amikamycin.

2) Add florfenicol preparation (hunojue), or neomycin, or amikamycin, or oxytetracycline to the feed for seven days.

3) Add sodium selenite vitamin E and electrolytic multivitamins (such as Vilikang) to drinking water for 7 days.

4) Do not get an emergency edema vaccine at this time. Because the attenuated vaccine takes seven days to produce immunity, and the inactivated vaccine takes 14 days to produce immunity, before the pigs develop immunity, there will be new patients in the group. In particular, attenuated vaccines can also promote susceptibility to swine disease.

5) Porcine edema is mainly caused by stress, especially stress caused by changes in feed. Therefore, stress should be minimized.

6) Selenium deficiency will increase the incidence of swine edema, so it is necessary to do a good job of selenium supplementation.

7) The incidence of edema disease is higher after the admission of purchased piglets, so they should be fed with broad-spectrum antimicrobials in the feed.
